XRIs: Metaidentifiers for a Metaidentity System
Drummond Reed

By the time of the Internet Identity Workshop, the XRI (Extensible Resource
Identifier) 2.0 specifications will be on their way to a vote as a full
OASIS standard, to be followed by the launch of global i-name and i-number
registry services from XDI.ORG (currently in beta by Identity Commons) as
well as the launch of a number of XRI-based services from i-brokers in
multiple market sectors.

The purpose of this talk is to explain where XRIs fit in an identity
metasystem - what problems they can and can't solve; how they are backwards
compatible with URLs, URIs, and IRIs; how they can serve as both
omnidirectional and unidirectional identifiers; what new kinds of privacy
protection they can provide; how they work with web services; and how almost
all Internet identity protocols can take advantage of this new layer of open
standard universal addressing infrastructure.
